Indeed, I assume it has something to do with the second law of thermodynamics. Just like you can't make electricity out of heat alone but need a temperature difference, here you need different concentrations of salt.
- _Microft 8y agoIf you want to read about some interesting stuff, you might wanna research "flux coupling". That is when one flux is used to pump another against a gradient, i.e. in the opposite direction as it would normally flow. That's pretty common in biological systems but there are physical cases as well when e.g. thermal and electric fluxes are coupled (Seebeck-/Peltier-effect).
